Cattle mutilations were prevalent from 1973 to 1983 in the United States. They were reported on in newspaper and magazine stories, including a documentary produced by Linda Moulton Howe for the Denver CBS affiliate.
The mutilations included the removal of genitals, rectums cored out to the colon, eyes missing and the tongue and throat cut with extreme surgical precision. The incisions were made cutting between the cells, actually separating molecular structure. This is why no blood was found at all, yet there was no vascular collapse.
